If you specify a virtual data
center as the target (/vcd/vcdId), the Metrics API
returns data for all the virtual machines in that data center and sorts the
data by timestamp; for example if you request 2 minutes of data and the virtual
data center has 2 virtual machines, the API returns data in the order:
vm1-timestamp1, vm2-timestamp1, vm1-timestamp2, vm2-timestamp 2.
